CONSTRUCTION OF LAM P-WICKS.

Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed March 30, 1906. Serial No. 308,841.

T 0 all whom, it may concern:

' Be it known that I, JAMEs H. MORRISON, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Construction of Lamp- Wicks; and I do declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in the construction of wicks for lampssuch, for example, as kerosene-oil lam s.

The objects of the invention are several: first, to provide means for increasing the illuminating capacity of the ordinary kerosene-oil lamp to a marked degree without causing the lamp to smoke; secondly, to increase the capillary attraction of the wick by returning the same in the form of a loop and uniting it in contact with the main feeding end of the wick immediately below its entrance into the burner, so that two sides of the wick are enabled to feed the burner.

It has been ascertained that the capillary attraction of the oil in the wick to the burner where a single length of the wick is depended upon to feed the burner is not sufficient to supply the burner, and as a consequence it is common practice to turn up the wick in an effort to increase the illuminating power of the lamp. This, as is well known, causes the lamp to smoke and endangers the chimney and is otherwise objectionable. The present invention obviates the above difficulties by providing means for supplying the burner with the requisite amount of oil at the consuming end of the wick.

Preceding a detail description of my invention, reference is made to the accompanying drawings, of which Figure I is a sectional elevation of a kerosene-oil lamp and a portion of the chimney thereof and in which my improvement is applied. Fig. II is a view of the burner detached and in which my improvements are applied. Fig. III is a sectional view on the line as a; of Fig. II.

In the specification similar reference characters indicate corresponding parts.

The lamp 0 is of a common construction and is likewise provided with a common form of burner which is mounted therein and supports the usual chimney e.

For the purposes of an illustration of my invention, which has no direct bearing upon the'form of lamp used, I have merely illustrated it in connection with an ordinary form of lamp, which is above briefly described.

The invention consists in forming the submerged wick lying within the body of the lamp in a loop, with its two portions a and 6 extending upwardly out of the oil to the burner, the portion a being connected to the burner by means of the usual feeding-shaft g. The portion of the wick which extends up through the burner is supported in position by means of a loop or metal band, which is secured and supported on the other end of the wick or that end which lies immediately below the burner and within the lamp. The other portion of said wickto wit, bis, as before stated, attached to the part a immediately below the burner and at such point is brought in close contact therewith in order that the portion a may be fed with oil for the burner, not only through the portion a,.but also through the part b, so that the capillary attraction into the burner is doubled. This has the effect of supplying the wick at the consuming end with the requisite amount of oil to provide a maximum candle-power and whereby the necessity of turning up the wick at intervals of short duration is avoided. The means for returning the wick end I) and uniting it to the portion a immediately below the burner consists of a metallic loop or band f, which is fastened to the extreme end of the portion 7) in any suitable manner. In the drawings, Fig. III, I have shown the end i of said band or loop passed through the portion 1) and clenched thereagainst in order that the attachment may be permanent. The portion a of the wick passes through the loop f, and the two parts are thus held together immediately below the burner. It is obvious that the two ends of the wick may be united at this point in a variety of ways and the same object be attainedto wit, looping the wick within. the oil and uniting the ends at the point of the burner.

I claim As a new article of manufacture, a lampwick doubled upon itself in the form of a loop and held together at a point immediately below the lower extreme end of the burner from which point only one side of said wick passes into the burner, the said wick so doubled being maintained in contact by means of a loop which is secured to the end of the wick which does not pass into the burner and through 10 in presence of two witnesses.
